Road Aesthetics

Exposing natural aggregate and asphalt for road aesthetics

The use of colours and natural finishes is now without doubt an extremely important element in the modern construction and landscaping of roads, highways, parking garages and bridges. Coloured and decorative surfaces can be used either purely aesthetically or to fulfil specific functional or design criteria. 


To satisfy this demand for coloured and decorative surfacing a plethora of products and methods are now available. Most of these use resins of some kind, which are applied to the existing surface and have aggregate particles mixed in or scattered on them.


These products often have bright artificial colours. They have varying degrees of success, most fade significantly after just a few months and many crack and fail after 12 to 18 months. When applied to asphalt surfaces, especially newly laid, failure is almost guaranteed, it's just a question of time.


Exposing Natural Aggregate Colours

Natural exposed aggregate asphalt gives the architect or designer the option to use locally available aggregates to compliment, contrast and enhance roads, car parking areas, footpaths, residential developments, town centres and urban areas.

The big potential benefit of only using naturally coloured aggregates is they will not fade and if incorporated in a standard asphalt mix design the colour will be all through the material, not just a coating on the top.




By using Blastrac shot blasting technology the surface binder is removed to allow the natural properties, specificities or colours of the aggregates to appear. This is a perfect answer to architects and cities permanent quest for innovation at a reasonable cost.


Exposing Aggregate on Asphalt Roads & Highways

Exposed aggregate asphalt provides a unique, new generation of distinctive asphalt surfaces with greatly increased aesthetic appeal and improved skid resistance while still giving all the functional qualities and durability of traditional asphalt.

Blastrac developed technologies to blast asphalt in order to successfully remove binders, rubber skid marks and pavement markings from asphalt roads, highways, parking garages and bridges without causing any detriment to the integrity or durability of the surface course material.
